TO ALL WHOM IT MAY CON OERN:

Beit known that I, CHARLES; H. BLANGBARD, of Boston, in the county ofSuffolk, and State of Massachusetts, have invented an Improved Machinefor Making Paste, Starch, Size, &o.; and I do hereby declare that thefollowing is a full and exact description thereof, reference being badto the accompanying drawings, and to the letters of reference markedthereon.

The'natu'rc of my invention consists in the combination and arrangementof the several parts of a machine for making paste, starch, size, 81.0.

To enable others skilled in the art to make and use my invention, I willproceed to 'describeits construction and use.

\ Drawings.

n o Figure l represents a perspective view of, mymachrue for makingpaste.

l Figure 2 is avertical section of the same.

Figure 3 is a plan showing the arrangement for giving reciprocatingmotion to the mirrors.

Figure 4 is a cross vertical section through the cooking-tank,represented by R, figs. 1 and 2 Figure 5 is a horizontal section,showing the radial brushes and the diaphragm.

I construct my machine as follows: A E E B D D C, fig, 1, form togethera frame or support, to which the several parts-of my apparatus ,areattached. H H, figs. 1 and 2, are metallic tanks, made with aconicalformed bottom, and connected together by the pipes P-P, shown infig. 2'; these tanks have near their bottoms the perforated diaphragms OO, fig. 2. I I represent two vertical shafts, to which are attached, bymeans of thearmgz-L, two upright slats M'M, anda'lso some stirrers N N.The object of the. vertical slats MM is to scrape or any flour that mayadhere to the walls of the tanks, and also to act together with the armsN N as 'stirrers.. At the lower ends of the shafts I I are attached a.number of radial arms, KK, figs. 2 and 5. The under sides of these armsare provided with stiff brushes, which rub "over and upon the diaphragmsO O. The action of these radial brush-arms thoroughly mixes and crushesany lumpsof flour which may have reached L the diaphragms, so thatnothing but thoroughly, mixed fluid shall pass into the lower part ofthe tanks. In fig.

2 1, are twostop-qochs, by means of which the fluid in'eithcr of thetanks may be allowed to pass into the pipes]? P. Q is a. nozzle, intowhich the pipes P P enter, and from which the fluid from either of themixingtanks may flow into the cooking-tank R. The mixing-shafts II donothave a continuous revolving motion, but a reciprocating motion that is,they make a partial revolution in one direction,'and then the motion isreversed; This motion is produced by the cord G G, which passes aroundthe pulleys X The ends of this cord are attached totbekuob Ic; this knobis forms part of slide, which isworked back and forth in the guide F bythe crank-shaft Z. The crank-shaft Z is operated by' the pin it in thewheel Y, fig. The object of this reciproeating motion is to give agreater agitation to the flour and water in the tanks, and thus cause amore thorough mixing of the ingredients. The cooking-tank R is made ofany suitable metal, andis provided with two hollow metallic rollcrs'SS,-which are connected through their journals to steampipes, which keepthem constantly hot, and, being made to revolve in the directionindicated by the arrows in fig. 4, the uncooked material is drawn downbetween them, and, being cooked in its passage, falls through theorifice U into the receptacle below. T T represent metallic plates; theobject of which is to scrape the cooked paste from the rollers, and thuscause it to fall through the orifice U. I

CZaim. What I claim as my invention, and desire to secure byLet tersPatent of the United States, is-- 1. The combination of the perforateddiaphragms 00 of the mixing-tanks with the revolving brushes-K K K,substantially as described and for the-purpose set forth.

ii. The device, or its mechanical equivalent, for giving the shafts I Iof the stirrers their reciprocating motion, substantially as described'and for the purpose set forth.

3. The combination and arrangement'of the hollow steam-heatedcooking-rolls S S substantially as described and for the purpose setforth. 7 v

e 4. The combination and arrangement of the cooking-tank R, the rolls SS, and the scrapers T T, substantially as describcdand forthepurp'oseset forth.

- 5. Thc'general construction, combination, and arrangement of theseveral parts of the machine, substantially as described and for thepurpose set forth.
